There were used the following equipment and devices:

• Seismometers of vertical and horizontal types with the frequency range 13 - 100 Hz;

• Tiltmeter with sensitivity < 1" of arc;

• Dosimeter-radiometer (ANRI-01-02);

• Ferrite antenna (non-standard operational frequency  100 MHz);

• Device for fluids sampling;

• System of digital registration of analogue signals and their envelopes.

Registered fields and signals had some features.

Seismic emission fields in form of seismic, seismic-emission and acoustic signals were recorded on side faces of pyramids in Dakhshur (pink and broken) and in Medume (irregular). For the latter - also in internal chamber.

One channel registered the seismic noises or their envelope, and the other channel registered the electric signal from ferrite antenna. Duration of registration was fron 20 minutes to 3-5 hours.

In addition, induced seismic emission was investigated in Dakhshur. On the top of small pyramid (near the broken) two channels simultaneously recorded the envelopes of the seismic noises with two seismometers: standard and high sensitive. During registration several shocks were made near the basement of the pyramid. In result there was observed the rise of envelope level during  10 minutes, which was ten times higher щи the top in comparison with the basement.

The simple comparison of other records has shown the higher level of the seismic-emission noise inside the pyramid and time coincidence of changing of signal from the ferrite antenna and seismic noises.

Other seismic pulse influences (shocks) were made for determination of: seismic velocities in pyramid's blocks, distance to the high-velocity basement for great pyramids, anomalous focusing of the seismic signal by the pyramid as the transformer of vibrations, anisotropy of the seismic response of the pyramid body subject to direction on the shock, probable unknown cavities inside the pyramid (Medume).

There were registered variations of tilts of the pyramids Gakhshur (broken) and Medume. Variations of tilts with some periodicities were registered in spite of high level if thermal noise.

The radiation background was measured inside and outside all investigated pyramids; for limestone, basalt and granite it was within the normal values. However, in the Pharaoh chamber (Hufu pyramid) the fresh split of granite has shown 35-37 mcR/hour; it was also detected that radioactivity of limestone inside the Medume pyramid is mach higher than for outer blocks.

There were analyzed the gas samples from the Pharaoh chambers (Hufu and pink pyramids). First sample had no significant differences with the standard, in the second sample there were detected the trace of hydrocarbons. The latter result is unusual and should be checked.

Probably the further processing will show some interesting properties of geophysical fields and signals in the pyramids of Egypt.
